Unpacked addons, how to edit addons while ArmA is running to see results after mission restart (or new mission editor preview).

It is very cool feature, to be able to run ArmA and edit your addon only to see the results in game almost real time (you have to restart the mission or press new mission editor preview) without exiting ArmA!

I could have saved hours of editing time if I'd known about this feature long time ago. The amount of times I've started, exited and started back up again ArmA is insane.

I don't know if this is the same thing, but I've always developed my scripts from the MyDocs/ArmA Other Profiles/DM/Scripts folder. Can use notepad++ and save on one monitor, and preview the test mission on the other. A very efficient way of developing. When the scripts are ready, I migrate them into their proper PBO folder.
